People say, "dogs are the most loyal friends of mankind." So our family also keeps a dog.

One day, my mother and I took him out to play. I am very tired. I saw him walking slowly, so I had to carry him home. He actually fell asleep slowly and comfortably in my arms. When I got home, I put it on the floor, and then I watched TV. Suddenly I saw a program about dog habits. I found the dog sleeping on TV, but it hid its head between its front legs. I subconsciously took a look at our puppy, which also hid its head in the middle of its front legs and slept soundly. Why is this? I looked at it carefully again, as if I was hiding my nose on purpose.

So I "investigated" its nose. I quietly put my finger between its two front legs and gently touched its nose. Its nose is wet, as if someone had sprayed water on it, which made me feel even more strange. Suddenly I remembered what my grandmother once said to me: "If a dog's nose is wet, it means it is very healthy." But this seems to have nothing to do with dogs hiding their noses when they sleep.

I looked up a lot of information with questions and finally found the answer. It turns out that dogs hide their noses to protect themselves from accidental injuries after falling asleep, which is the instinctive reflection of dogs. A dog's nose is much more complicated than that of other animals, so its nose is much more sensitive than that of other animals. The nose is really important to a dog's life. If the sense of smell is partially damaged, it will bring great inconvenience to the life of dogs.

Therefore, even if dogs let other animals hurt their bodies, they will not hurt their noses.
